292 PHENOL. 



Phenol-ethylenether, (C 6 H 5 .O) 2 C 2 H 4 , is produced 

 in the same way from phenol-potassium and ethylene 

 bromide. Colorless crystals ; fusing point, 95. 



Phenol-acetate, C 6 H 5 .O.C 2 H 3 0. Is obtained by heat- 

 ing phenol with acetyl chloride. Colorless liquid, 

 boiling at 190. 



Phenol-succinate, (C 6 H 5 .0) 2 C 4 H 4 2 , is obtained by 

 the action of succinyl chloride on phenol. Laminae 

 of a mother-of-pearl lustre ; fusing point, 118 ; boiling 

 point, 330. 



Phenol-carbonate, (C 6 H 5 .0) 2 CO. By heating 

 phenol with carbonyl chloride at 140-150. Colorless, 

 shiny needles ; fusing point, 78. 



t Phenol-cyanate, CO.KC 6 H 5 , is obtained by distil- 

 ling ethyl phenylcarbamate (p. 263) with phosphoric 

 anhydride. Colorless liquid ; boiling point, 163 ; 

 yields diphenylurea when brought together with water. 



Chlorine substitution- pro ducts of phenol. Or- 



thochlorphenol, C 6 H 4 C1.0H, is produced by the ac- 

 tion of chlorine or sulphuryl chloride (S0 2 C1 2 ) on 

 phenol. Colorless crystals, insoluble in water, easily 

 soluble in alcohol ; fusing point, 41 ; boiling point, 

 2I8.Dichlorphenol, C 6 H 3 C1 2 .OII. Colorless, six-sided 

 needles ; fusing point, 42-43 ; boiling point, 209. 

 Trichlorphenol, C 6 H 2 C1 3 .OH. Long, colorless needles, 

 fusing point, 67-68 ; boiling point, 244. Moderately 

 strong acid. Pentachlorphenol, C 6 C1 5 .OH. Shiny, 

 white needles ; fusing point, 185. 



Bromine substitution-products. Orthobromphe- 

 nol, C 6 H 4 Br.OH. Colorless liquid ; cannot be distilled 

 without decomposition. Dibromphenol, C 6 H 3 Br 2 .OH. 

 Colorless crystalline mass ; fusing point, 40. Tribrom- 

 phenol, C 6 H 2 Br 3 .OH. Long, fine, colorless needles ; 

 fusing point, 95. Tetrabromphenol, C 6 HBr 4 .OH, and 

 pentabromphenol, C 6 Br 5 .OH, are produced by heating 

 tribromphenol with bromine at 180-220, Both com-
